Child psychology is one of the many branches of psychology and one of the most frequently studied specialty areas. This particular branch focuses on the mind and behavior of children from prenatal development through adolescence. Child psychology deals not only with how children grow physically, but with their mental, emotional, and social development as well.

Historically, children were often viewed simply as smaller versions of adults. When Jean Piaget suggested that children actually think differently than adults, Albert Einstein proclaimed that the discovery was "so simple that only a genius could have thought of it."
